【摘要】：納米纖維是一維納米材料的典型代表,具有超大的比表面積、獨(dú)特的物理化學(xué)特性而受到人們關(guān)注,納米纖維可被用于能源、催化、納米電子器件、環(huán)保過濾、紡織工程、環(huán)境空氣治理等方面。制備納米纖維的技術(shù)有很多種,其中靜電紡絲技術(shù)以其裝備簡(jiǎn)單、成本低廉、高效便捷、制備納米纖維種類多受到人們關(guān)注,而被廣泛應(yīng)用。氧化鋅材料作為一種新型的寬禁帶材料,具有較寬禁帶、很高的電子遷移率、非常小的介電常數(shù)而且導(dǎo)電性能比較好等優(yōu)點(diǎn),特別適于制作藍(lán)綠光發(fā)光二極管、激光器、壓電傳感等電子器件。而納米氧化鋅將其優(yōu)點(diǎn)進(jìn)一步擴(kuò)大,可以制作靈敏度更高的傳感器件、效率更高的催化器件等。如何開發(fā)、應(yīng)用納米氧化鋅材料已成為科學(xué)界關(guān)注的焦點(diǎn),要充分發(fā)揮氧化鋅材料的優(yōu)越性能和電子器件方面的開發(fā),需要我們深入了解氧化鋅的各種性質(zhì)。我們已知純的氧化鋅是N型半導(dǎo)體材料,此外還可以通過簡(jiǎn)單的摻雜制備其他特殊性質(zhì)的N型氧化鋅,目前N型氧化鋅半導(dǎo)體早已成功制備并投入應(yīng)用。制備穩(wěn)定的P型氧化鋅尚且存在一系列問題,對(duì)于氧化鋅電子器件的應(yīng)用開發(fā)有重要意義。第二章介紹了通過靜電紡絲技術(shù)制備鑭摻雜的P型氧化鋅納米纖維。具有典型鈣鈦礦結(jié)構(gòu)的Ba TiO3擁有眾多獨(dú)特的性質(zhì),被譽(yù)為電子陶瓷工業(yè)的支柱,是電子陶瓷元器件的基礎(chǔ)材料。隨著器件向集成化、小型化發(fā)展,納米電子器件得到人們廣泛關(guān)注。鈦酸鋇有很好的濕敏傳感特性、壓電特性并且在超級(jí)電容器領(lǐng)域也有潛在應(yīng)用。因此制備鈦酸鋇納米纖維變得意義非凡,成為研發(fā)的焦點(diǎn)。第三章介紹了通過靜電紡絲的方法成功制備了鈦酸鋇納米纖維,并研究了煅燒溫度對(duì)鈦酸鋇納米纖維形貌的影響,此外我們利用離心靜電紡絲的方法成功制備了高取向平行的鈦酸鋇納米纖維,并通過實(shí)驗(yàn)驗(yàn)證了其對(duì)濕度響應(yīng)快速靈敏,具有很好的濕敏特性。此外,我們還做了利用靜電紡絲的方法制備鈣鈦礦納米纖維,用于太陽(yáng)能電池的探究性工作。太陽(yáng)能電池一直以來被人們認(rèn)為是解決當(dāng)前資源、能源危機(jī)最好的方法,傳統(tǒng)硅基太陽(yáng)能電池已經(jīng)發(fā)展幾十年,生產(chǎn)消耗大、污染重。近年來具有鈣鈦礦結(jié)構(gòu)的太陽(yáng)能電池,以極快的發(fā)展速度吸引著人們的眼球,目前報(bào)道的鈣鈦礦太陽(yáng)能電池轉(zhuǎn)化效率已超過20%。在鈣鈦礦太陽(yáng)能電池中,起至關(guān)重要作用的就是鈣鈦礦層,也是電池的光吸收轉(zhuǎn)化層,利用靜電紡絲的方法制備鈣鈦礦納米纖維層替代原先的鈣鈦礦層,充分發(fā)揮了納米纖維超大比表面積的優(yōu)勢(shì),對(duì)于提高鈣鈦礦太陽(yáng)能電池的轉(zhuǎn)化效率,促進(jìn)太陽(yáng)能電池的發(fā)展有至關(guān)重要的意義。
[Abstract]:Nano fiber is a typical one-dimensional nano material, with large surface area, unique physicochemical properties and attention, nano fiber can be used for energy, catalysis, nano electronic devices, environmental protection filter, textile engineering, environmental governance and other aspects. The preparation of nano fiber technology has many kinds, including electrostatic spinning technology with its simple equipment, low cost, convenient and efficient preparation of nano fiber type more attention, and has been widely used. Zinc Oxide material as a new type of wide band gap materials with wide band gap, high electron mobility, dielectric constant is very small and the conductive good performance etc. the advantages, especially suitable for the production of blue and green light emitting diodes, lasers, piezoelectric sensors and other electronic devices. The utility model has the advantages of nano Zinc Oxide will further expand, can make a sensor with higher sensitivity, higher efficiency High catalytic devices. How to develop the application of nano materials, Zinc Oxide has become the focus of attention of scientific community, to give full play to the development of superior performance of electronic devices and Zinc Oxide materials, we need to know all kinds of Zinc Oxide. We know Zinc Oxide is pure N type semiconductor material, also can through the preparation of other special properties doping N type simple Zinc Oxide, currently Zinc Oxide N semiconductor has been successfully prepared and used. The preparation of stable P Zinc Oxide still has a series of problems, has important significance for the application and development of Zinc Oxide electronic devices. The second chapter introduces the Zinc Oxide P nano lanthanum doped fiber prepared by electrospinning. With a typical perovskite structure. Ba TiO3 has many unique properties, known as the pillar of electronic ceramics industry, is the basic material of electronic ceramic components Material. With the device to integration, miniaturization, nano electronic devices are widely concerned. Barium titanate humidity sensing properties have good piezoelectric properties, and have potential applications in the field of super capacitors. So the preparation of barium titanate nano fibers become meaningful, become the focus of research of the third chapter. The success of the electrospinning method to prepare barium titanate nano fiber, and studied the effect of calcination temperature on barium titanate nano fiber morphology, moreover we use the method of centrifugal electrostatic spinning high orientation barium titanate nanofibers were prepared in parallel, and validated its quick response to humidity sensitive, with wet sensitive characteristics very well. In addition, we also made use of electrospinning method for preparing perovskite nano fiber, used to work exploring solar cells. The solar cell has been recognized by people To solve the current resources is the best method of energy crisis, the traditional silicon-based solar cell has several decades of development, production and consumption, heavy pollution. In recent years, a solar cell with a perovskite structure, with the fast pace of development to attract people's attention, the perovskite solar cell conversion efficiency is reported more than 20%. in perovskite solar cell, which play a vital role is perovskite, and battery light absorption layer for preparing perovskite nano fiber layer instead of the original perovskite layer by electrospinning method, give full play to the nano fiber large surface area advantage, to improve the conversion efficiency of solar cell perovskite is essential to promote the development of solar energy. The significance of the battery.
